Just had mechanic give me results of compression test on my "73 1.7.
#1 100 psi #2 120 psi #3 120 psi #4 150 psi He is recommending valve job. I realize the readings are all over the place, but is this guy right? Car was in for valve adjustment, small miss at 2800 RPM, and backfire under decell. Timing and fuel mixture were adjusted. Backfire is still there, but not too bad. Still not smooth accel at 2800 - 300 RPM. During last oil change, I noticed some black soot around the left exhaust pipe on the cylinder head. Can't remember if it was the front or rear cylinder.I suspect small exhaust leak. Would this leak have any bearing on the compression reading for that cylinder? I would appreciate any and all comments on the valve job recommendation and your thought on the compression readings. Thanks for listening! |
